摘要:
为了比较油气水平释放及垂直释放时的扩散规律，利用Gambit软件，建立水槽模型，在FLUENT中进行溢油后油气扩散的模拟，分析了不同泄漏方向及不同泄漏速度下油气的扩散规律与分布情况。模拟结果表明：油气分别在水平泄漏和垂直泄漏后的运动轨迹不同，前者呈J形，后者呈S形；水平泄漏的扩散范围相比垂直泄漏的扩散范围大，垂直泄漏到达水面需要的时间较短；泄漏速度越大，油气扩散的速度就越快，污染的范围就越广。
Abstract:
The diffusion law of horizontal release and vertical release of underwater oil and gas are numerically simulated in this paper.Gambit software was used to establish the tank model，and the simulation of oil and gas diffusion after oil spill was carried out by FLUENT.The movement and distribution of oil and gas under different leakage directions and different leakage velocities were analyzed.The simulation results show that the trajectory of oil and gas are different between horizontal leakage and vertical leakage，the former is in J shape and the latter is in S shape，and horizontal leakage has a larger range of diffusion than vertical leakage，it takes a shorter time to reach the water surface vertically;The greater the rate of leakage，the faster the diffusion of oil and gas，and the wider the range of pollution.
